Kedarnath Bhattacharaya (born 20 October 1957), better known as Kumar Sanu, is an bollywood Indian playback singer who mainly sings for Hindi and Bengali films.
In 1989, Jagjit Singh introduced Kumar Sanu to Kalyanji-Anandji in Mumbai. On their suggestion, he changed his name from "Kedarnath Bhattacharya" to "Kumar Sanu" because his voice and singing style were much influenced by Kishore Kumar. Sanu then relocated to Mumbai, where Kalyanji-Anandji gave him a chance to sing in the film Jaadugar.
For the 1990 film Aashiqui, music directors Nadeem-Shravan got Sanu to sing all but one of the songs. He won the first of his record five consecutive Filmfare Awards as Best Male Playback Singer. His next Filmfare Awards came for songs in the movies Saajan (1991), Deewana (1992), Baazigar (1993) and 1942: A Love Story (1994). He won 5 back to back Filmfare awards for singing, between 1990 and 1994.
